Question

What is the sum of the interior angles of an equilateral Pentagon whoose sides is 5inches long

Answer 1

To determine what is the sum of the interior angles of any polygon, we can use the following expression:

`\begin{gathered} (n-2)\cdot180 \\ n=\text{ number of vertices} \\ (5-2)\cdot180=540 \end{gathered}`

The sum of the interior angles of an equilateral (regular) pentagon is 540°.
